The ARPANET made its first host-to-host connection in October of 1969 and from there slowly grew into a behemoth, laying the groundwork for our modern internet. The good folks over at Smithsonian magazine recently GIF'd the growth of the ARPANET from 1969 to 1977. But why stop there?

The ARPANET is almost gone by 1989, though the lights wouldn't officially be turned off until July of 1990.

Frustratingly, I can't for the life of me find a geographical map of the ARPANET for 1985. If you see one hiding somewhere please send it my way so that we can add it. RIP ARPANET.
